[PATCH 3/3] i2c: enable async suspend/resume on i2c client devices

From: Derek Basehore <dbasehore@chromium.org>

This enables the async suspend for i2c client devices. This reduces
the suspend/resume time considerably on platforms where i2c devices
can take a lot of time (hundreds of ms) to resume.
